I never made one. Load the Y4 configuration and then do "show motor layout" to know what KK2 expects. Generally, left front rotates one way, right front rotates the other way, rear bottom rotates some way, and rear top rotates opposite of rear bottom.
One rear motor points straight up and the other points straight down.
